[TILES-V2-2]: add new column to table_metadata

[pregnantboy]

Changes

Added a new db column to the table_metadata table to distinguish between PostgreSQL and DynamoDB tables.

What changed?

• Created a new migration file 20250506071427_add_table_metadata_db_column.ts that adds a db column to the table_metadata table with a default value of 'ddb' and not nullable constraint
• Updated the TableMetadata model to include the new db property with type 'pg' | 'ddb'

How to test?

1. Run the migration
2. Verify the column exists in the database schema
3. Check that existing records have the default 'ddb' value
